I have always enjoyed building tunnels.
I always liked to see a train disappear into a tunnel then try to figure out where the other end is.
So I pulled out my Dad HO scale catalog and searched for good model.
I came across the famous Moffet tunnel. I liked the West end as it had more detail to it.
It was some what of a simple construction.
I would have like to have the arc over the entrance more circular.
But I think I really captured the look of the tunnel and I am happy with the results.
On the West end there are buildings that are next the entrance.
But I had trouble modeling them correctly.
